Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic GF7 and Panasonic GF6 side-by-side from the front, back and top in their relative dimensions. Panasonic GF7 has external dimensions of 107 x 65 x 33 mm (4.21 x 2.56 x 1.3″) and weighs 266 g (0.59 lb / 9.38 oz) (including batteries). Panasonic GF6 has external dimensions of 111 x 65 x 38 mm (4.37 x 2.56 x 1.5″) and weighs 323 g (0.71 lb / 11.39 oz) (including batteries).
Below you can see the front view size comparison of Panasonic GF7 and Panasonic GF6. Panasonic GF7 is 4mm narrower and 5mm thinner than Panasonic GF7 but they have the same height of 65mm.
Here is the back view size comparison of Panasonic GF7 and Panasonic GF6.
Now lets look at the top view comparison of Panasonic GF7 and Panasonic GF6.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic GF7 is significantly lighter (57g ) than the Panasonic GF6 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since both Panasonic GF7 and Panasonic GF6 have the same Micro Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Unfortunately neither Panasonic Lumix DMC-GF7 nor Panasonic Lumix DMC-GF6 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
